ENGINE ATTACHMENT.

Application filed January This invention relates to internal combustionengines of that type having a splash system of lubrication and has forits object the provision of an attachment adapted to be mounted at thebase of the cylinder block for forming substantial continuations of thecylinders so that the pistons will be enclosed even when they projectbelow the bottom of the block, the advantage being that there will beless oil splashed onto the cylinders and consequently greater economy inoil consumption and a reduction of carbonization and likelihood offouling the plugs.

An important object is the provision of an attachment of this characterwhich is designed to be installed upon already existing engines withvery little trouble, the device being moreover simple and inexpensive tomake, easy to install, efficient in use, durable in service and ageneral improvement in the art.

With the above and other objects and advantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, inwhich:

Figure 1 is a bottom plan View of a portion of an engine block showingthe engine applied,

' Figure 2 is a vertical longitudinal section,

Figure 3 is a vertical cross section on the line 33 of Figure 1,

Figure 4 is a vertical cross section on the line 44 of Figure 1,

Figure 5 is a perspective view of the device detached.

Figures 6 and 7 are views of modifications.

Referring more particularly to the drawings the letter A designates acylinder block formed with the cylinders I3 and crank case portion C.The letter I) indicates the cam shaft which operates the push rods FM Itis well known that the cylinders themselves are separated by a web F atwhich is pro vided a lug G.

In carrying out the present invention I provide an attachment which isformed preferably as a single casting and which includes an elongatedbody 10 of a length to be disposed between the bearings H and I on theblock. This body is formed with two cylindrical recesses 11 designed toregister with. the bores of the cylinders 13 when the body is securedflat against 2, 1924. Serial No. 684,043.

the underside of the block. At its outermost ends the body is cut awayas indicated at 12 so as not to interfere with the bearings, and at oneside its upper surface is beveled at 13 to lie against the crank caseportion C of the block. The bottom wall 14 is formed with elongatedopenings 15 for the passage of the connecting rods J of the motor, andthe body is also formed with openings 16 at the side opposite thathaving the beveled edges 13 likewise to permit the necessary movement ofthe connecting rods.

To effect mounting of the device, I pro vide a hole 17 which is formedtherethrough in the web portion 18 which is at the center of'the body orbetween the recesses 11, and through this hole is passed a stud 18 whichis screwed into a tapped hole 19 in the block. body has a flat face 20adapted to lie conformingly against the lug 20 and'projecting from thisflat face is a bracket like projection 21 formed with a cavity 22adapted to engage and receive the lug G, the cavity being of such sizeand shape as to fit neatly upon this lug.

IVhile it is true that the opposite side of the device might be attachedin substantially the same manner, that is: by means of a stud or thelike, I preferably form the upper surface of the body at the center ofits opposite side with an upstanding projection 22 which fits within acavity 28 formed originally in the block. This projection 22 has itsunder surface hollowed out as indicated at 24. The device is designedprimarily for use in connection with a Ford engine and it-appears thatin the later models the cylinder block is not provided with a cavity 23.In applying my device to this type of block it becomes necessary eitherto grind or otherwise gouge out the material of the block to define acavity or else to omit the projection 22 entirely and to rely entirelyupon the securing stud 18 or to provide two of such studs one at eachside of the engine. These two alternative modifications are illustratedin Figures 6 and 7; the former of which shows the device as held by asingle stud, and the latter of which shows the use of two studs.

In the use of the device, it will be seen that when the pistons reachthe lower ends of their strokes and project beyond the bottom of theircylinders they will still be enclosed by the attachment except at theThe intermediate portion of the cut may 1 emits 12 and it is thereforeobvious that on y a limited quantity of oil may be splashed onto thepistons. When the pistons are at any other position, the "attach mentWill operate to'prevent excessive oil;

from being splashed onto the cylinder Walls. As a consequence it isapparent that excessive oiling and Waste of oil together with theresultant disadvantage of carbonization and plug fouling will beprevented while at the same time ample lubrication will be insured; Thedevice Will not in any Way interferewi'th the operation of the engineand it is to be noted that it is simple to make and may be readilyapplied Without involving any changes inrthe bloclr other than themaking of a hole therein.

comprising a body member formed to extend across a pair of cylinders andhaving flanges registering with and forming continuations of thecylinder Walls, the body member having its bottom and portions of itssides open to accommodate the connecting rod, a projec'tion on one sideof the body member fitting Within thespace between the cylinders topreventshifting of the body, a lug on one side of the body engaging uponan existing projection on the cylinder block, 'and a stud passingthrough said lug.

An engine attachment comprising a body 'member adapted fordisposition against the bottomof a cylinder block and formed withrecesses registering Withthe cylinder bores, the bottoms of the recesseshaving 0 a'enin'gs for the accommodation of the connecting rods and theends of the body having cut away portions to expose limited areas of thepistons and means for securing the body in'po'sition, comprising a studpassing through the body and screwed'into a tapped hole in theblock, andlugs projecting from one side of the body and fengageabl'e with anexisting project-ion on the block.
